My 2010 GMC acadia slt rolls backward on inclines even though the transmission is in drive. I have driven automatic transmission vehicles for years and in my experience they are not supposed to roll backward in drive. If anyone is behind the vehicle when this occurs they could very well be crushed. The dealership stated this is normal behavior, but this is not and they should be required to fix…

What stands out
Owners have filed 36 powertrain complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
No new NHTSA powertrain complaint has been filed on this vehicle in over 15 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: The 2010 Acadia has well-documented powertrain defects—timing chain stretch, transmission wave-plate failure, and shift issues—that mirror problems GM recalled in 2007–2009 models but refuses to cover in 2010. Expect costly repairs ($2,800–$4,000+) and dealer dismissal if you buy one used; GM will not stand behind the vehicle once it's past five years or 100,000 miles.
Owners consistently report three interconnected powertrain defects that GM deliberately excluded from coverage despite using identical parts in 2010 models that failed in 2007–2009 counterparts.
Timing chain stretch is the most widespread complaint. The chain stretches, guides wear, and the engine throws multiple codes (P0300, P0301, P0303, P0305, P0008, P0017) along with a check engine light. Some vehicles fail to start; others produce loud rumbling from the engine bay. Repairs run $2,000 to $4,000. GM issued extended warranties (10 years/120,000 miles) for 2007–2009 Acadias and explicitly excluded 2010 models, even those manufactured in 2009 with identical components.
Transmission wave-plate failure causes slipping, difficulty shifting (especially 3rd to 4th gear), whining, and jerking. One wave-plate cracked at 79,000 miles; complete rebuilds or replacements cost $2,800–$3,000. GM's recall #14404 (Special Coverage: Transmission Clutch Wave Plate) covers 2008–2009 models only; 2010 VINs are explicitly excluded despite using the same parts.
Transmission shift hesitation and rough shifts occur intermittently, particularly 2nd to 3rd gear, and may be undiagnosable during dealer test drives. A restart temporarily fixes the problem, but the root cause remains unaddressed.
A secondary complaint involves vehicles rolling backward in drive or park on inclines; dealers claim this is "normal behavior" rather than a defect.

Failure modes owners describe
Timing chain stretch and guide wear
Timing chain stretches, guides wear, or both stretch and guides fail together. Owners report this as a known defect affecting 2007–2009 Acadias under extended warranty (10 years/120,000 miles or special coverage #11340) but the 2010 model year is not covered by GM despite identical parts and failure mechanisms. Early 2010 units manufactured in 2009 also denied coverage.
When: 51,000 to 137,882 miles; one failure reported at 9,400 miles post-transmission replacement
Symptoms owners cite: Check engine light illumination; Multiple diagnostic codes (P0008, P0303, P0305, P0017, P0300, P0301 reported in one case); Crankshaft sensor codes; O2 sensor codes; Loud rumbling noise from engine; Vehicle fails to start or stalls on restart; Hesitation during acceleration or uphill driving
Codes mentioned: P0008, P0303, P0305, P0017, P0300, P0301, Camshaft correlation code (stretched timing and chain guides)
Repairs/costs cited: Complete timing chain assembly replacement; costs cited: $2,000–$4,000. One owner: dealer paid half of repair at 51,000 miles under goodwill. Dealers attribute issue to stretched chains and worn guides. GM reduced recommended oil-change intervals on 2010 but did not recall or replace defective chains.
Recalls/TSBs owners mention: Extended warranty/special coverage (10 years/120,000 miles or special coverage #11340) issued for 2007–2009 models; 2010 model year explicitly excluded despite identical parts. GM refuses to extend coverage to 2010 units, even those manufactured in 2009. One owner received 50% dealer goodwill repair; most others denied coverage.
Transmission wave-plate failure
Wave plate inside transmission cracks or fails (3/5 wave-plate failure noted in one case), leading to internal damage and necessitating complete transmission rebuild or replacement. GM issued recall #14404 (Special Coverage: Transmission Clutch Wave Plate) for 2008–2009 models but did not extend it to 2010 despite identical parts and failure modes.
When: Intermittent onset; one case at 79,000 miles, another at 79,100 miles; slipping can begin early and worsen over time
Symptoms owners cite: Transmission slipping (RPMs increase without proportional acceleration); Difficulty or failure to shift into or out of specific gears (commonly 3rd to 4th); Hard shifting, especially on inclines; Whining noise from transmission; Jerking or abrupt starts after a stop; Transmission codes set; Hesitation in acceleration; vehicle barely moves despite high RPMs
Codes mentioned: Shifter stuck code, Multiple transmission codes (specific codes not detailed in narratives), Transmission failure code
Repairs/costs cited: Complete transmission rebuild or replacement required; costs cited: $2,800–$3,000+. Owners report the issue is known in the industry; one shop stated the vehicle is 'notorious for transmission issues.' One owner's transmission was replaced, then failed again at 9,400 miles.
Recalls/TSBs owners mention: Recall #14404 (Special Coverage: Transmission Clutch Wave Plate) issued for 2008–2009 models; 2010 model year excluded by VIN despite identical parts. GM explicitly states affected VINs are not included, even though 2009 transmission components were used in early 2010 production. One owner traded in vehicle; GM offered only $2,000 toward a new purchase.
Transmission shift hesitation and rough shifting
Transmission fails to shift smoothly or delays shifting, particularly from 2nd to 3rd gear. Issue is intermittent and unpredictable; restart sometimes resolves it temporarily. Described as 'something sticking' in the transmission by one mechanic. Separate from wave-plate failure.
When: Early in ownership (reported at 60,000 miles on purchase); intermittent and recurring
Symptoms owners cite: Hesitation in shifting from 2nd to 3rd gear (occasionally fails to shift); Rough or hard shifts; RPM fluctuation during shift attempts; Issue resolves temporarily with vehicle restart (1–3 restarts sometimes required); Unpredictable occurrence; cannot be diagnosed consistently even during dealer test drives; Transmission not responding to shift commands
Repairs/costs cited: One mechanic diagnosed 'something sticking' in the transmission and recommended full transmission replacement, but the exact internal component was not identified in narratives. No repair costs specified for this specific symptom.
Transmission does not hold in park or drive on inclines
Vehicle rolls backward or forward when in park or drive on inclines, particularly when driver moves foot from brake to accelerator. Multiple owners report dealer dismissal, claiming this is 'normal behavior' or 'the vehicle is performing according to its design.' Safety hazard in traffic and parking situations.
When: Intermittent; one case reported from ~10,000 miles onward; ongoing issue
Symptoms owners cite: Vehicle rolls backward when in park on uphill incline; Vehicle rolls backward when in drive on uphill incline; Rolls when driver lifts foot from brake to accelerator at traffic light; Rolls when parking (caused one incident of vehicle bumping a pedestrian); Occurs without warning
Repairs/costs cited: Dealer inspected one vehicle and 'altered the transmission so it was performing according to its design.' No further action taken. Vehicle remains unfixed.
Recalls/TSBs owners mention: Dealer stated behavior is normal and 'according to design.' No recall or service bulletins mentioned. One case from 2010 remains unrepaired as of multiple updates through 2012.
Battery premature drain and cell failure
Vehicle kills cells in batteries prematurely, forcing multiple replacements. Batteries fail to hold charge. Reported within first 3 years of ownership.
When: Within 3 years of purchase; 2016 purchase had 2 battery replacements by complaint date
Symptoms owners cite: Dead or dying battery; Multiple cells killed in battery; Key unable to be removed from ignition switch (transmission shift cable failure led to vehicle remaining powered on, draining battery in one case)
Repairs/costs cited: Battery replacements (2 reported); costs not specified. In one case, shift cable failure caused vehicle to remain powered, draining battery.
Engine overheating
Engine overheats shortly after startup, even on short drives. Air conditioning blows warm air. Temperature gauge maxes out. Vehicle displays 'powering down engine' message. One case reported on low-mileage vehicle (~36,000 miles) with minimal use.
When: At 36,000 miles; after long drive followed by 19-hour parking period
Symptoms owners cite: Engine overheating immediately upon restart; Temperature gauge maxes out; Air conditioning blows warm instead of cold; 'Powering down engine' warning message displayed; Vehicle becomes unusable
Repairs/costs cited: No repair narrative; vehicle owner concerned about warranty coverage (over 3 years old at time of complaint).
Shift cable failure
Shift cable fails, preventing transmission from being shifted properly. Key becomes stuck in ignition and cannot be removed. Shift indicator does not display correct gear. Vehicle remains powered on, draining battery.
When: At 70,000 miles
Symptoms owners cite: Shift gear very difficult to shift; Key cannot be removed from ignition switch; Vehicle remains on after ignition key failure to remove; Shift indicator does not display proper gear; Battery drains due to vehicle remaining powered
Repairs/costs cited: Shift cable replaced by dealer.
Recalls/TSBs owners mention: Manufacturer not notified.
Gear shift fails to respond
Transmission gear shift mechanism fails to work or respond while driving at various speeds. Separate complaint instances with no clear resolution.
When: At approximately 70,529 miles
Symptoms owners cite: Gear shift fails to work while driving; Issue recurs several times; Vehicle becomes uncontrollable
Repairs/costs cited: Vehicle not diagnosed or repaired at dealer.
Recalls/TSBs owners mention: Manufacturer not contacted.
Engine power loss and reduced-power mode
Vehicle enters reduced-power mode while driving, limiting acceleration and performance. Traction control and StabiliTrak stability control turn off. Engine management system goes into limp mode.
When: Intermittent; ongoing throughout ownership
Symptoms owners cite: 'Engine in reduced power' warning message; Traction control off; StabiliTrak (stability control) warning: 'Service StabiliTrak'; Loss of acceleration; Inability to maintain highway speeds
Repairs/costs cited: No repair specifics provided.
Power steering fluid leak
Power steering fluid level drops continuously, requiring frequent topping-up. Owners are told powertrain must be replaced and that GM is aware of the problem but refuses to fix it.
When: Ongoing maintenance issue; timing not specified
Symptoms owners cite: Power steering fluid level drops continuously; Frequent need to add fluid to maintain level
Repairs/costs cited: Power train (powertrain) replacement recommended by mechanic; cost not specified.
Recalls/TSBs owners mention: GM aware of problem and refuses to address per owner's account.

Timing belt issues!
Transmision slips in drive on hills. It actually rolls backwards when you take your foot of the brake. Even when the transmision is in gear
